Template Literals

Tagged templates differ from regular template literals in that they are processed by a function (the 'tag') before producing a result. When you prefix a template literal with a function name, that function receives the template's string parts and interpolated expressions as arguments, giving you complete control over how the template is processed. This allows for powerful customizations such as creating DSLs (Domain-Specific Languages), implementing template safety features like automatic escaping of HTML, applying styling (as in the styled-components library for React), internationalization, and more. While regular template literals always evaluate to strings with interpolated values, tagged templates can return any value type, as determined by the tag function's implementation.
